JOHN H. PETTIT, OF GREAT FALLS, MONTANA.

, AUTO-SPRING OILER.

Application filed August 26, 1920.

T0 all'whom it may concern:

Be it known that I, JOHN H. Pn'r'rrr, c1t1- zen of the United States,residing at Great Falls, in the county of Cascade and State of Montana,have invented certain new and useful Improvements in Auto-Spring Oilers,of which the following is a specification, reference being had thereinto the accompanying drawings.

This invention relates to an auto spring oiler, and has for its objectthe construction of a simple and efficient oiling or lubricating devicefor automobile springs, that can be quickly attached or detached at thewill of the operator.

With this and other objects in view, my invention comprises certainnovel combinations, constructions and arrangements of parts as will behereinafter described, illustrated in the accompanying drawings, andmore particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a perspective view of a device constructed in accordancewith the present invention, shown attached to a spring, while- Fig. 2 isa sectional view taken on line 2-2, Fig. l, and looking in the directionof the arrows.

Fig. 3 is a sectional view of another embodiment of the presentinvention, while Fig. 4 is a perspective view of the same.

Fig. 5 is a fragmentary, perspective View of an end of anotherembodiment of the spring clamps of the device.

Referring to the drawings by numerals, 1 designates the spring of theusual laminated structure. My spring oiler device comprises a pair ofinverted, substantially U-shaped spring clamps 2, and attached at 3, tothe ends of these clamps, are plates 4. Each plate 4.- is provided withinwardlyextending, horizontal prongs 5 upon their upper and lower edges,which prongs hold the flat wick 6 from being displaced off the side ofthe spring 1 after the device has been placed upon said spring. Attachedto the outer face of each plate 4. is a reservoir or tank 7, containingthe lubricant. Through aperture 8 of each plate 4c, extends an auxiliarywick 9, which wick 9 is connectedto the flat wick 6, so that the oil inthe tank 7 will readily pass to the flat wick 6, thence be distributedbetween the layers of the spring 1.

Specification of Letters Patent.

- Patented NOV. 1, 1921.

Serial No. 406,222.

In the embodiment shown in Figs. 3 and 4, only one plate 4 is used, andupon corresponding ends of the springs 2, at 10, are attached a doubleprong device 11, the prongs of which device extend inwardly and areadapted to be positioned between portions of the layers constituting thespring 1, see Fig. 3, whereby the device is held securely upon thespring 1 against accidental displacement.

In the embodiment shown in Fig. '5, the prongs, instead of being formedupon the prong device 11, are integral with the spring clamp 2.

lVhile I have described the preferred embodiments of my invention, andhave illustrated the same in the accompanying drawings, certain minorchanges or alterations may appear to one skilled in the art to whichthis invention relates, during the extensive manufacture of the same andI, therefore, reserve the right to make such alterations or changes asshall fairly fall within the scope of the appended claims.

What I claim is:

1. In a device of the class described, the combination of an elongatedplate provided with a series of inwardly-extending prongs on itslongitudinal edges, a tank attached to said plate, a wick on said platebetween and secured by said prongs, an auxiliary wick extending throughsaid plate into said tank and in communication with said firstmentionedwick, and a pair of bowed spring clamps attached directly to the outsideof said plate for holding the plate upon a spring.

2. In a device of the class described, the combination of a plateprovided upon its upper and lower edges with a series ofinwardly-extending horizontal prongs, a flat wick against said platebetween and secured by said prongs, a tank against said plate on theopposite side to said wick, said plate provided with an aperture openinginto said tank, an auxiliary wick extending through said aperture andconnected to said firstmentioned wick, and substantially U-shaped springclamps secured to the outside of said plate between its edges forholding the same upon a spring.

3. In a device of the class described, the combination of a plate, atank and a Wick in communication with said tank carried by said plate, aspring clamp fastened to the outside of said plate, a prong devicecarried by one end of said clamp and provided with a plurality ofprongs, and the prongs of said prong device adapted to be positionedbetween portions of a spring for preventlng accidental displacement ofthe device 01f the spring.

4. In a device of the class described, the oomblnatlon With a spring, ofa W1Ck and a tank against one slde of sald spring, a

prong device against the opposite side of 10 said spring, and a clampstraddling said spring and having one end fastened directly to saidprong device and its other end fastened to and supporting said Wick andtank against the spring.

In testimony whereof I hereunto affix my signature.

JOHN H. PETTVIT.
